DCEM-4MS Dual-channel DC energy meter is a highly integrated product for DC parameter measurement. When used with a shunt or external Hall sensor, it can accurately measure 1-2 channels DC voltages and 1-2 channels DC currents (with direction), power, total electricity, each single-circuit electricity, and other electrical parameters, and can be equipped with optional DI modules.
DCEM-4MS has RS485 and supports MODBUS-RTU communication protocol, which can upload the collected data and equipment status. DCEM-4MS is widely used in electric power, communications, railways, transportation, environmental protection, steel, and other industries to monitor the current and power consumption of DC equipment.
